When the number of the plurality of proximity sensors 87 that detects a companion animal over the set time increases during the operation of the pump 20, the control unit C increases the number of companion animals that have approached the companion water feeder to eat water. It can be judged that the pumping capacity of the pump 20 can be increased. The control unit C may increase the pumping capacity of the pump 20 by increasing the rotational speed of the rotor of the pump 20. Increasing the pumping capacity of the pump 20 may have the same meaning as increasing the rotational speed of the rotor of the pump 20.

If the number of the plurality of proximity sensors 87 detecting the companion animal over the set time is reduced during the operation of the pump 20, the control unit C may receive a portion of the plurality of companion animals and consume water from the companion animal waterer. Judging that it is far away, the pumping capacity of the pump 20 can be reduced. The control unit C may reduce the pumping capacity of the pump 20 by reducing the rotational speed of the rotor of the pump 20. Reducing the pumping capacity of the pump 20 may have the same meaning as reducing the rotational speed of the rotor of the pump 20.

For example, during operation of the pump 20, the control unit C includes two of the first proximity sensor 87A, the second proximity sensor 87B, the third proximity sensor 87C, and the fourth proximity sensor 87D. When the dog detects the companion animal for a set period of time or more, it is determined that two companion animals have approached the companion water feeder to eat water, and the pump 20 can be operated with a second pumping capacity greater than the first pumping capacity.

In addition, the control unit (C), the operation of the pump 20, three of the first proximity sensor (87A), the second proximity sensor (87B), the third proximity sensor (87C) and the fourth proximity sensor (87D) is rejected When the animal is sensed for a predetermined time or more, it is determined that three companion animals have approached the companion water feeder to drink water, and the pump 20 can be operated with a third pumping capacity greater than the second pumping capacity.

In addition, the control unit (C) during the operation of the pump 20, the first proximity sensor (87A), the second proximity sensor (87B), the third proximity sensor (87C) and the fourth proximity sensor (87D) are all companion animals When is detected for more than the set time, it is determined that four companion animals have approached the companion water feeder to eat water, and the pump 20 can be operated with a fourth pumping capacity greater than the third pumping capacity.

The control unit (C) receives a signal from the proximity sensor 87 and determines whether the companion animal has approached the companion animal water supply within a predetermined distance range, and when it is determined that the companion animal has approached within a predetermined distance range, operates the pump 20 to supply water. If it is carried out and it is determined that it has not been approached within a predetermined distance range, the operation of the pump 20 can be stopped. Here, the control unit C may operate the pump 20 only when the companion animal continues to approach the set time for a predetermined time or more within a predetermined distance range.

In addition, when it is determined that a plurality of companion animals have approached by receiving a signal from a plurality of proximity sensors 87, the control unit C increases the pumping capacity of the pump 20 to correspond to the number of approached companion animals. Water can be provided to provide enough water for your pet.

In addition, the control unit (C) continuously stores and analyzes the operating time of the pump 20 according to the signal from the proximity sensor 87, and determines the time and the amount of water that the companion animal regularly drinks water at any time, and determines The pump 20 may be operated to provide a water supply amount at a water supply time.

Referring to FIG. 16, in the control method of the companion animal water supply device according to the fifth embodiment of the present invention, at least one of the plurality of proximity sensors 87 detects the companion animal in the companion animal detection step (S51).

Thereafter, the control unit C determines whether at least one of the plurality of proximity sensors 87 detects the companion animal or more. That is, in the determination step S52, the control unit C determines whether at least one of the plurality of proximity sensors 87 detects the companion animal for a predetermined time or longer.

As a result of the determination step (S52), if the time at which one of the plurality of proximity sensors 87 detects the companion animal is less than the set time, the companion animal approaches the companion animal water supply for a while and then the It is determined that it is far from the companion animal water supply, and the logic can be returned to the companion animal detection step (S51).

In addition, as a result of the determination step (S52), the control unit (C), if at least one of the plurality of proximity sensors 87 detects the companion animal is longer than the set time, after the companion animal approaches the companion animal waterer It is judged that it is staying in order to drink water, and the pump 20 can be operated. That is, in the pump operation step (S53), the control unit (C), when at least one of the plurality of proximity sensors (87) detects the companion animal for more than the set time, the companion animal approaches the water supply to the companion animal and eats water. It is judged that it is staying in order to operate, and the pump 20 is operated. In other words, in the pump operation step (S53), the control unit (C), when at least one of the plurality of proximity sensors 87 starts to detect the companion animal, when the set time passes, the companion animal approaches the companion animal waterer After that, it is determined that it is staying in order to drink water, and the pump 20 is operated.

After the pump operation step (S53), the control unit C determines whether the plurality of proximity sensors 87 do not detect the companion animals for a predetermined time or longer. That is, in the determination step S54, the control unit C determines whether all of the plurality of proximity sensors 87 do not detect the companion animal for a predetermined time or longer.

As a result of the determination step (S54), if at least one of the plurality of proximity sensors 87 detects the companion animal for a predetermined time or longer, the control unit C determines that the companion animal is continuously eating water in the companion animal water supply device. , It may return the logic to the pump operation step (S53).

In addition, as a result of the determination step (S54), if the plurality of proximity sensors 87 do not detect all of the companion animals for a set time or longer, the companion animal eats water from the companion animal waterer and then the companion animal waterer. It is judged as being away from, and the operation of the pump 20 is stopped. That is, in the pump stop step (S5), the control unit (C), if a plurality of proximity sensors 87 do not detect the companion animal for more than a set time, the companion animal eats water from the companion animal waterer and then the companion animal It is determined that it is far from the water supply, and the operation of the pump 20 is stopped. In other words, the control unit (C) in the pump stop step (S55), after a set time after the plurality of proximity sensors (C) does not detect the companion animal, the companion animal eats water from the companion animal waterer and then It is determined that it is far from the companion animal water supply, and the operation of the pump 20 can be stopped and the logic can be terminated.

On the other hand, after the pump operation step (S53), the control unit (C) determines whether the number of proximity sensors (87) for detecting a companion animal over a set time is increased. That is, in the determination step S56, the control unit C determines whether the number of the proximity sensors 87 for detecting the companion animal for a set time or longer is increased.

As a result of the determination step S56, if the number of the proximity sensors 87 for detecting the companion animal for a predetermined time or more is not increased, the control unit C determines that the number of companion animals coming to drink water with the companion animal waterer is not increased. , It may return the logic to the pump operation step (S53).

In addition, as a result of the determination step S56, when the number of the proximity sensors 87 for detecting the companion animal for a predetermined time or more is increased, the control unit C determines that the number of companion animals coming to drink water is increased. , It is possible to increase the pumping capacity of the pump 20. That is, in the pumping capacity increase step (S57), the control unit C determines that when the number of proximity sensors 87 for detecting a companion animal for a predetermined time or more is increased, the number of companion animals coming to drink water with the companion animal water supply is increased. Thus, it is possible to increase the pumping capacity of the pump 20 and return the logic to the determination step S54.

On the other hand, after the pump operation step (S53), the control unit (C) determines whether the number of proximity sensors (87) for detecting a companion animal over a set time is reduced. That is, in the determination step S58, the control unit C determines whether the number of the proximity sensors 87 detecting the companion animal for a predetermined time or more is reduced.

As a result of the determination step S58, if the number of the proximity sensors 87 detecting the companion animal for a set time or longer is not reduced, the control unit C determines that the number of companion animals who come to drink water with the companion animal waterer is not reduced. , It may return the logic to the pump operation step (S53).

In addition, as a result of the determination step S58, when the number of the proximity sensors 87 detecting the companion animal for a predetermined time or more is reduced, the control unit C determines that the number of companion animals who come to drink water with the companion animal waterer is reduced. , It is possible to reduce the pumping capacity of the pump 20. That is, in the pumping capacity reduction step (S59), the control unit (C) determines that when the number of proximity sensors (87) for detecting a companion animal for a set time or more is reduced, the number of companion animals who come to drink water with the companion animal water supply is reduced. Thus, it is possible to reduce the pumping capacity of the pump 20 and return the logic to the determination step S54.

As described above, according to the control device and control method of the companion animal water supply according to an embodiment of the present invention, a plurality of proximity sensors 87 are installed spaced apart from each other along the circumference of the companion animal water supply to provide companion animals within a predetermined distance range. Since the sensing unit, and the control unit C operates the pump 20 when at least one of the plurality of proximity sensors 87 detects the companion animal for a predetermined time or longer, the companion animal approaches the companion animal water supply unit and sets the set time. Since the pump 20 is operated only when it stays over, power consumption can be reduced.

In addition, according to the control device and control method of the companion animal water supply according to the embodiment of the present invention, depending on the number of the plurality of proximity sensors 87 for detecting the companion animal over the set time during the operation of the pump 20, Since the pumping capacity of the pump 20 is adjusted, the pumping capacity of the pump 20 can be adjusted according to the number of companion animals approaching the pet water supplyer and staying above the set time.

Hereinafter, with reference to FIGS. 17 and 18, a control method of the water supply according to the inclination of the water tank according to the sixth embodiment of the present invention will be described.

In general, when the water supply is settled on the ground and operates normally without external force, it is not necessary to consider the tilt of the water tank. However, when a force is applied to the water supply by a companion animal, user, or other external factors while the water supply is being performed, an accident such as tilting or overturning of the water supply may occur. If the position of the water supply becomes unstable, contact with the water supply The pet in an easy-to-understand position may be electrocuted or there may be various other risks of injury to the pet. Therefore, there is a need for a method of controlling the water supply to prevent such a risk as much as possible.

As part of the countermeasures as described above, the water supply device according to the present invention detects the tilt of the water tank and cuts off the power of the water supply when the water supply is inclined to prevent an electric shock of a companion animal.

While the power of the water supply is turned on and the water supply process is performed through the pump 20 (S61), the gyro sensor 88 detects the slope of the water tank 10 (S62) and transmits it to the control unit C. The control unit C determines whether the inclination of the water tank is greater than a preset first inclination set value (S63).

The first slope setting value may be a value that can be overturned when the slope setting value is exceeded, or even if the rollover is not overturned, significant shaking occurs in the process of restoring to the original position, which may cause an electric shock hazard to the companion animal. It may be a value.

When the inclination of the water tank is smaller than the first inclination set value, the power supply of the water supply is maintained (S67), but when the inclination of the water tank is larger than the first inclination set value, the water supply is turned off for a preset time. (S64) Prevent pets from electric shock.

After the set time has elapsed, the control unit compares the inclination of the water tank with the first inclination set value (S65), and when the inclination of the water tank is greater than the first inclination set value, shuts off the water supply during the set time (S64). ) However, if the inclination of the water tank is smaller than the first inclination set value, power is supplied to the water supply again (S66) so that water supply can be achieved.

As described above, it is intended to prevent electric shock and injury of the companion animal by shutting off the power, but there is still a risk of electric shock and injury when tilted at a considerable angle even before the first tilt setting value is tilted.

Therefore, according to the seventh embodiment of the present invention, in order to compensate for the above-described problems, when the water tank is inclined above the second slope setting value smaller than the first slope setting value before the power is turned off, in order to inform the danger. By turning on the warning light or generating a warning sound, a pet or a user can prevent the danger of electric shock or injury.

Therefore, when the second slope set value is reached, the danger light is first alerted to the user and the companion animal through the lighting of a warning light or the occurrence of a warning sound, and when the tank reaches the first slope set value more inclined than the second slope set value. In order to protect the companion animal by shutting off the power, a two-stage protection device was provided.

Referring to FIG. 19, the power of the water supply is turned on and the water supply process is performed through the pump 20 (S71), the gyro sensor 88 detects the slope of the water tank 10 (S72), and the control unit ( C). The controller C determines whether the inclination of the water tank is greater than a preset second inclination set value (S73).

The second slope set value is set to a slope smaller than the first slope set value, and is set to a slope that is smaller than the first slope set value, but may have a minimum risk of electric shock or injury risk to the companion animal in the slope. You can.

When the inclination of the water tank is greater than the second inclination set value, the warning light 91 may be turned on with the light of the first color or an alarm sound may be generated through the warning sound generating device 92 (S74). The first color and warning sound is preferably formed of a color and sound that can sense the danger of the companion animal.

If the slope of the water tank is determined to be greater than the first slope set value after the warning light turns on and the warning sound is generated (S75), the water supply is turned off for a set time (S76). The warning light and the warning sound generating device may not work after the power is cut off, and the warning light and the warning sound generating device may be operated by the auxiliary power supply device even after the power is cut off.

If the inclination of the water tank is smaller than the first inclination set value, it is determined whether or not it is greater than the second inclination set value (S78). At this time, when the inclination of the water tank is greater than the second inclination set value, turn on a warning light and turn on a warning sound generating device. A warning sound can be generated (S74), and when the inclination of the water tank is smaller than the second inclination set value, the power supply of the water supply is maintained as before (S79).

After turning off the water supply for the set time (S76), the control unit (C) again determines the slope of the water tank, and if the slope of the water tank is greater than the first slope set value (S77), the power of the water supply for the set time again When the slope of the water tank is smaller than the first slope set value, it is determined whether the slope of the water tank is greater than the second slope set value (S78). At this time, if the slope of the water tank is greater than the second slope set value, the warning light can be turned on and a warning sound can be generated (S74). When the slope of the water tank is less than the second slope set value, the power supply of the water supply is maintained as before ( S79).

The power supply can be cut off and re-supplied through opening and shorting of switches installed in the circuits constituting the wireless power transmitter 72 or the wireless power receiver 73.

The configuration other than the control method according to the seventh embodiment of the present invention is the same as the configuration according to the sixth embodiment of the present invention described above.

Hereinafter, a control method of a water supplyer according to a change amount of a slope of a water tank according to an eighth embodiment of the present invention will be described with reference to FIGS. 17, 20, and 21. The configuration other than the control method to be described later is the same as the configuration according to the sixth embodiment of the present invention described above.

In addition to cutting off the power supply according to the tilt of the water tank, it may also be necessary to cut off the power supply according to the amount of change in the tilt of the water tank. The large amount of change in the inclination of the tank means that the tank is inclined rapidly due to the large external force acting on it. As a result, the companion animal may not respond to the tank having a sudden movement, which may lead to an unexpected electric shock or injury. In addition, it is also necessary to control the water supply system to prevent this danger as much as possible because the companion animal may receive a great impact when it comes into contact with a water tank having a sudden movement.

While the water supply is powered on and the water supply process is being performed through the pump 20 (S81), the gyro sensor 88 detects the amount of change in the tilt of the water tank 10 (S82) and transmits it to the control unit C . The control unit C determines whether the amount of change in the gradient of the water tank is greater than a preset first set amount of change in gradient (S83).

The first slope change amount set value may be a value that can cause the water supply to overturn if the slope change amount set value is exceeded, or even if it cannot be overturned, considerable shaking may occur in the process of recovering to the original position, which may result in an electric shock hazard to the companion animal. It may be a set value.

When the amount of change in the inclination of the water tank is smaller than the first gradient change amount, the power supply of the water supply is maintained (S87), but when the amount of change in the inclination of the water tank is larger than the first gradient change amount set value, Shut off the power (S84) to avoid electric shock to your pet.

After the set time has elapsed, the controller again compares the amount of change in the slope of the water tank with the set value of the first amount of slope (S85), and when the slope of the water tank is greater than the set value of the first amount of change in the water tank, the power of the water supply is turned on again for the set time. Block (S84), but if the amount of change in the slope of the water tank is smaller than the set value of the first change in slope, supply power to the water supply again (S86) so that the water supply can be made.

As described above, it is intended to prevent electric shock and injury of the companion animal by shutting off the power supply, but when there is a significant amount of gradient change even before the first gradient change amount is reached, there is still a risk of electric shock and injury.

Therefore, according to the ninth embodiment of the present invention to compensate for the above-described problems, when the water tank is tilted more than the second slope change amount set value smaller than the first slope change amount set value before the power is turned off, the risk In order to inform, the warning light was turned on or a warning sound was generated so that the pet or the user could prevent the danger of electric shock or injury. Therefore, when the second slope change amount is reached, the user is alerted to the danger to the user and companion animal by first turning on the warning lamp or generating a warning sound, and the tank is tilted faster than the second slope change amount, so that the amount of change in the slope of the tank is reduced. 1 When the slope change amount reaches the set value, a two-stage protection device is provided to protect the companion animal by shutting off the power.

Referring to FIG. 21, while the power of the water supply is turned on and the water supply process is performed through the pump 20 (S91), the gyro sensor 88 detects the amount of change in the tilt of the water tank 10 (S92), and controls it. (C). The control unit C determines whether the amount of change in the gradient of the water tank is greater than a preset second set amount of gradient change (S93).

The second slope change amount set value is set to a value smaller than the first slope change amount set value, and is smaller than the first slope change amount set value, but may be set to a value that may cause a minimum electric shock risk or injury risk to the companion animal. have.

When the amount of change in the gradient of the water tank is larger than the second set amount of change in gradient, the warning light 91 may be turned on with the light of the second color or an alarm sound may be generated through the warning sound generating device 92 (S94). The second color and the warning sound is preferably formed of a color and sound that can sense the danger of the companion animal. The first color and the second color may be formed in different colors or may be formed in the same color.

When it is determined that the amount of change in the inclination of the water tank is greater than the set value of the first amount of inclination after the warning light is turned on and the warning sound is generated (S95), the water supply is turned off for a set time (S96). The warning light and the warning sound generating device may not operate after the power is cut off, and the warning light and the warning generating device may be operated by the auxiliary power supply device even after the power is cut off.

If the amount of change in the inclination of the water tank is smaller than the set value of the first gradient, it is determined whether the amount of change in the second gradient is greater than the set value (S98). Turn on and generate a warning sound through the warning sound generating device (S94), and if the inclination of the water tank is smaller than the second slope change amount set value, the power supply of the water supply is maintained as before (S99).

After turning off the water supply for the set time (S96), the control unit (C) again determines the amount of change in the tilt of the water tank, if the slope of the water tank is greater than the set value of the first gradient change (S97), the water supply for the set time again When the power of the tank is turned off and the amount of change in the inclination of the water tank is smaller than the set value of the first gradient, it is determined whether the amount of change in the inclination of the water tank is greater than the set value of the second inclination (S98). At this time, if the amount of change in the slope of the tank is greater than the set value of the second gradient, the warning light can be turned on and a warning sound can be generated through the warning sound generating device (S94). As it is, the power supply of the water supply is maintained (S99).

The configuration other than the control method according to the ninth embodiment of the present invention is the same as the configuration according to the sixth embodiment of the present invention described above.

Hereinafter, a control method of a water supply plate according to a slope of a water tank according to a tenth embodiment of the present invention will be described with reference to FIGS. 22 to 26. The configuration other than the control method to be described later is the same as the configuration according to the sixth embodiment of the present invention described above.

As described above, in order to solve the water supply imbalance problem for each approach direction that may occur when the water supply is located on the inclined surface, the tenth embodiment according to the present invention detects the inclination of the water tank through the gyro sensor and corrects the inclination. The water supply plate 30 can be maintained horizontally.

When the water supply plate is kept horizontal, since the amount of water flowing over the water supply plate can be formed constantly regardless of the direction, the amount of water falling from the edge of the water supply plate is also constant regardless of the direction, and likewise, the companion animal approaches from any direction It is possible to receive the proper amount of water regardless of whether or not.

While the power of the water supply is turned on and the water supply process is performed through the pump 20 (S101), the gyro sensor 88 detects the slope of the water tank 10 (S102). When the detected information is transmitted to the control unit C, the control unit calculates a tilt direction and an angle through which the water supply plate 30 can maintain a horizontal level through tilt correction, and controls the tilt of the water supply plate based on the information. (S103), the water supply plate may be kept horizontal (S104). Likewise, since the tilt of the water tank may be changed for reasons such as installing the water tank in another place, the tilt correction process and the tilt control process of the water supply plate may be repeatedly performed unless the water supply is terminated (S105).

Hereinafter, with reference to FIG. 25, the configuration of the water supply unit 3000 and the water supply unit rotating body 5000 for rotating the water supply plate through the tenth embodiment according to the present invention will be described. Configurations other than the configuration of the water supply unit and the water supply unit rotation body to be described later are the same as those according to the sixth embodiment of the present invention described above.

The tenth embodiment according to the present invention, in order to control the inclination of the water supply unit 3000 including the water supply plate 3100, the light guide plate 3700, the partition plate 3300, and the like, on the lower side of the water supply unit 3000 A water supply part rotating body 5000 is provided, and the water supply part rotating body 5000 may rotate the water supply part 3000 so that the water supply plate 3100 can be maintained horizontally.

The water supply unit 3000 is connected to a water supply plate 3100 through which water supplied from the water supply hole flows, a water supply hole 3200 communicating with the water supply pipe to the water supply plate, a partition plate 3300, and a pump to connect the water to the water from the pump. The water supply pipe (3400) transferred to the water supply plate, coupled to the lower side of the water supply unit, and inserted into the water supply unit rotation guide (5100), moves along the water supply unit rotation guide to determine the slope of the water supply unit according to its movement position (3500) ), A moving part supporting part 3600 for connecting and supporting the water supply part and a moving part, a light guide plate 3700 provided on the outer part of the water supply part, and the like.

The configuration of the water supply plate 3100, the water supply hole 3200, and the partition plate 3300 is the same as that of the sixth embodiment. The water supply pipe 3400 is connected to the pump in the same way as in the sixth embodiment, but in the tenth embodiment of the present invention, the water supply unit 3000 can be tilted and rotated at the same time, so the water supply pipe 3400 has elasticity. It can be formed of a flexible material. Therefore, the water supply pipe can be bent, and the water transferred from the pump can be stably supplied to the water supply plate 3100 regardless of rotation and movement of the water supply pipe 3400. In the tenth embodiment of the present invention, the water supply pipe is formed of a bellows hose, but is not limited thereto, and can be formed of a water supply pipe of various materials that are elastic.

The moving part 3500 may adjust the inclination angle of the water supply plate 3100 while moving through the water supply part rotation guide 5100. The moving part is movable by a second motor (not shown) that has received a signal from the controller C. In addition to the second motor, various devices for moving the moving part can be used. Through the movement of the moving part, the water supply plate 3100 may form an inclination in the vertical direction of the water supply.

The moving part support 3600 is provided in combination with the moving part so that the moving part 3500 is movable through the water supply part rotation guide 5100 without being detached from the water supply part rotation guide 5100. The moving part support 3600 connects the moving part 3500 and the partition plate 3300, and is formed under a predetermined distance from the rotating body base 5300 below the moving part support 3600 to form a rotating body ( 5300) and the moving part supporting part 3600 is formed to prevent abrasion due to contact.

The material of the light guide plate 3700 is made in the same way as the sixth embodiment of the present invention, but in the outer shape, the tenth embodiment is convex as the curvature equal to the curvature of the water supply part support 5200 to be described later unlike the sixth embodiment. It is formed, so that the rotation of the water supply unit 3000 can be performed without difficulty.

The water supply part rotating body 5000, when the moving part 3500 is inserted so that the moving part 3500 of the water supply part 3000 can be moved, when the water supply part rotation guide 5100 and the water supply part 3000 are rotated The water supply part support 5200 serving to support the water supply part, the rotation body base 5300 formed on the lower side of the water supply part rotation body 5000 to support the water supply part and the water supply part rotation body, the lower part of the rotation body base 5300 It is formed on the water supply unit includes a first motor 5400 for rotating the rotating body 500 in the horizontal direction.

The water supply part rotation guide 5100 includes a rectangular opening having a predetermined curvature, and the moving part 3500 of the water supply part 3000 can be inserted through the opening, and the inserted moving part 3500 is curvature. When moving through the formed opening, the entire water supply unit 3000 combined with the moving unit may rotate and move along the curvature of the water supply unit rotation guide 5100. Therefore, when the moving part 3500 moves along the water supply part rotation guide 5100, the water supply part 3000 may determine the inclination of the water supply plate 3100 according to the moving position of the moving part 3500.

The water supply unit support 5200 may support the water supply unit 3000 to be rotatable. The water supply part support 5200 is formed with the same radius of curvature as the light guide plate 3700 and may serve as a guide for movement of the light guide plate 3700 when the water supply part 3000 rotates. In addition, it may be formed of the same material as the light guide plate 3700, through which the light of the light emitter can be transmitted to the outside regardless of whether the water supply unit 3000 is rotated.

The rotating body base 5300 is formed to support all the components of the water supply unit 3000 and the components of the water supply unit rotation body 5000. In addition, through the first motor 5400 formed on the lower side of the rotating body base 5300, the rotating body base may rotate in the horizontal direction. As the rotating body base rotates in the horizontal direction, the entire water supply part rotating body 5000 and the water supply part 3000 rotate simultaneously.

Hereinafter, a process of adjusting the inclination angle (S103) of the water supply plate will be described with reference to FIGS. 25 and 26.

The tilt signal detected by the gyro sensor 88 is detected by the control unit C, and the control unit C transmits a motor control signal according to the tilt correction value of the water supply plate 3100 to the first motor 5400 and the second motor ( (Not shown).
